A prefab second skin can make old apartments net zero

Built-in insulation helps dramatically cut energy use.

A German startup is offering a new way for old buildings to potentially reach net-zero status: adding a prefabricated second skin.
 
Ecoworks begins the process with a 3D scan of an old building, both inside and out, creating a digital twin. The model is then sent to suppliers and a factory, where most of the second skin is prefabricated, including windows, ventilation, and channels for pipes.
 
The resulting new envelope includes a modular roof with built-in solar panels. Construction workers can install a facade panel at the site in 20 minutes. A full building conversion, including replacing fossil-fuel-powered heat, can be done in a few weeks.
 
Ecoworks uses AI to identify buildings best suited to its approach. Simple, block-like apartment complexes are top choices, but the company plans to expand to schools and single-family homes. It also has plans to offer its services in other countries.

Brazil Olympics spurring green construction

Brazil's green building industry will expand in the coming years, spurred by construction of low-impact venues being built for the 2016 Olympics. The International Olympic Committee requires arenas built for the 2016 games in Rio de Janeiro meet international standards for low-carbon emissions and energy efficiency. This has boosted local interest in developing real estate with lower environmental impact than existing buildings. The timing couldn’t be better: the Brazilian government is just beginning its long-term infrastructure expansion program.

Just how green is that college campus?

The College Sustainability Report Card 2011 evaluated colleges and universities in the U.S. and Canada with the 300 largest endowments—plus 22 others that asked to be included in the GreenReportCard.org study—on nine categories, including climate change, energy use, green building, and investment priorities. More than half (56%) earned a B or better, but 6% got a D. Can you guess which is the greenest of these: UC San Diego, Dickinson College, University of Calgary, and Dartmouth? Hint: The Red Devil has turned green.
